HENRY STEN Z, OF FARIBAULT, MINNESOTA, ASSIGNOR OF ONE-HALF TO JOSEPH J.WEYER, OF SAME PLACE.

ELECTRIC-LIG HT SHADE.

SPECIFICATION forming part of Letters Patent No. 559,149, dated April28, 1896.

Application filed IT 1111? 1895- To all whom it may concern.-

Be it known that I, HENRY STENZ, a citizen of the United States,residingat Faribault, in the county of Rice and State of Minnesota,- haveinvented a new and useful Electric- Light Shade, of which the followingis. a specifioation.

This invention relates to an improvement in electric-light shades, beingdesigned especially for use in connection with incandescent lights.

The object of the present invention is to provide an improved shadewhich is capable of being adjusted to any desired pointcircumferentially and at any angle with relation to the globe and socketof an ordinary incandescent light.

A further object of the invention is to pro vide novel means forautomatically retaining the shade at any desired adjustment.

In order to accomplish the objects mentioned, the invention consists inan improved electric-light shade embodying certain novel features anddetails of construction and arrangement of parts, as hereinafter fullydescribed, illustrated in the drawings, and finally pointed out in theclaims.

In the accompanying drawings, Figure 1 is a perspective View of one ofthe improved shades, the same being shown applied to an incandesccntelectric lamp. Fig. 2 is an enlarged perspective View of the improvedshade detached. Fig. 3 is a detail plan view of the spring clip orclasp, showing the manner of combining the locking spring-platetherewith.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings.

Referring to the drawings, 1 designates the shade proper, which may beform ed from any preferred material, the inner surface thereof being ofa light color and glossyfinish, adapting the same to serve as areflector, while the outer surface is preferably of some dark colorwhich will be agreeable to the eyes. This shade is preferably madepear-shaped, re-

sembling the bulb of the incandescent fixture and of an areasufficiently greater than said bulb to prevent the rays of lighttherefrom from reaching the eyes of the user.

2 designates a spring clip or clasp, which is Serial No. 554,214. (Nomodel.)

made from a sheet-metal blank and bent to comprise a pair of spring armsor clasps 8, the extremities of which are curved in a reverse" directionto form flaring ends or hooks 4, adapting the clip to be more readilyintroduced around the metal socket of an incandescent lamp. Thesespring-arms will ordinarily be sufficient to hold the clip and the shadecarried thereby in position upon the lamp-bracket; but, if desired, ascrew 5 may be employed passing through the extremity of one of saidspring-arms and into athreaded socket in the opposite arm, whereby thearms may be firmly clamped around the socket of the lamp. It is alsodesirable in some cases to lock the extremities of the spring-armstogether by means of a metal strip or plate 7, which is given a gradualcurve, as shown, and has its ends bent or hooked in a reverse direction.This strip or plate 7 is engaged with the spring-arms by passing itshooked ends over the flaring hooked extremities of the spring-arms ofthe clip, as shown in Fig. 3, the central portion of said plate bearingagainst the lamp-socket and aiding materially in holding the springclasp or clip 2 in place.

The clip 2 is formed with a pair of outwardly-projecting perforated ears8, which are formed by making incisions in the central portion of theclip and bending the portions bounded by such incisions laterally oroutwardly from the main body of the clip, as shown. These ears areadapted to receive between them the looped end of a hinge-plate 9,secured to the inner upper end of the shade 1, a pin or rivet beingextended through said ears and hinge-plate for uniting the shade 1 andclip 2 pivotally.

1O designates an eye-plate, which is secured to the outer surface of theshade 1, and bent to comprise an outward or laterally extending portion11, and again bent inwardly, as shown at 12, to form a pocket, in whichis placed a rubber washer 13. The portions 11 and 12 of the eye-plate 10are formed with alining perforations 14, and the soft-rubber washer 13is also formed with a smaller perforation in alinement with theperforations 14:, and adapted to receive and permit the passagetherethrough of the outer end or extremity of a sliding arm or rod 15,the inner end of which is formedwith an eye or loop in engagement with aperforated laterally-extending ear 16 on the clip 2. The gage of the armor rod 15 is in excess of the diameter of the perforation in the rubberWasher 13, by means of which the arm or rod is adapted to slide withinsaid washer with an amount of friction capable of supporting the shade 1at any desired angle or elevation.

If desired, the eye-plate 10 and also the hinge-plate 9 may be formedwith. integral pointed spurs or extensions, which may be bent at rightangles thereto and passed through the material of the shade and clinchedupon the opposite side for holding said plates in place, as shown.

By means of the construction above described a very simple, inexpensiveand efficient incandescent-lamp shade is provided, which is capable ofbeing adjusted circumferentially or at any desired angle or elevationwith relation to an incandescent lamp.

The improved shade may also be applied readily and easily to anyincandescent lamp, and may be as readily removed therefrom, whendesired.

It will be apparent that rubber washers or other friction devices may beused at the hinged joint between the shade and clip for holding theformer at any angle desired, and that other changes in the form,)roportion and minor details of construction may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of thisinvention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. A lamp-shade comprising a clasp member for engaging the lamp, theshade member hinged directly to the clasp member, and an arm connectedto one of said members and having a longitudinally-sliding andfrictional engagement with the other member and serving to adjust theangle of the shade, substantially as described.

2. In a lamp-shade, a spring-clasp adapted to be engaged with the lamp,in combination with the shade hinged at one edge directly to said clasp,a friction device carried by said shade, and a friction slide-rodconnected to said clasp and engaging the friction device on the shade,substantially as specified.

3. In a lamp-shade, a spring-metal clasp, the shade proper hingedthereto, an eye-plate carried by said shade, a rubber washer supportedby said eye-plate, and a sliding rod connected at one end with the claspand working at its opposite end through a perforation in said rubberwasher, all arranged for joint operation, substantially as specified.

4. In a lamp-shade, a clasp having oppositelydisposed springarms formedwith hooked extremities, in combination with the shade proper hinged atone edge to said clasp, means for adjusting the shade with relation tothe clasp, and a C-shaped locking-plate formed with hooked ends, saidlocking-plate having a sliding engagement with the hooked extremities ofthe spring-arms of the clasp and adapted to interlock therewith,substantially in the manner and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

HENRY STENZ.
